Apparently I dropped a landscape timber on a Garter snake (8 inches), two days ago, that was resting under the pile. There was a little blood around his mouth when I found him but none since. He lifts his head but holds it a 45 degree angle and twirls like an Alligator. I see no signs of damage to his body or head. I have him in a bed or dry leaves and vegetation and a shallow tray of water. Did I hit him or is this some kind of Garter Snake disease? Also, what should I do to help him get better?
